Description

本発明は、群管理運転制御される複数台のエレベータを制御するエレベータの制御装置に係り、特に地震の揺れを受けて休止したエレベータを復旧させるのに好適なエレベータの制御装置に関する。   The present invention relates to an elevator control device that controls a plurality of elevators that are controlled in group management operation, and more particularly to an elevator control device that is suitable for restoring an elevator that has been stopped due to an earthquake shake.

従来より、群管理運転制御される複数台のエレベータには、地震が発生したときに各エレベータの異常を点検し、異常の有無に基づいて復旧あるいは適切な処理を行うエレベータの制御装置が備えられている。このエレベータの制御装置は、地震発生時に所定以上の揺れがあったときに地震管制運転させ、この地震管制運転により休止したエレベータを監視装置を介して、復旧の要否を判定する地震復旧診断運転させる運転制御を行っている。   Conventionally, a plurality of elevators that are controlled in group management operation have been equipped with an elevator control device that checks the abnormality of each elevator when an earthquake occurs and restores or performs appropriate processing based on the presence or absence of the abnormality. ing. This elevator control device operates in seismic control when there is more than a predetermined vibration at the time of the earthquake, and the earthquake restoration diagnosis operation that determines the necessity of restoration of the elevator stopped by this seismic control operation via the monitoring device Operation control is performed.

このように運転制御されたエレベータが地震の揺れを受けると、地震管制運転が行われて各エレベータが休止する。各エレベータが休止した後、地震復旧診断運転が行われ、これらの休止したエレベータのかごを走行させて異常の有無を確認し、復旧の診断を行う。そして、エレベータに異常が検出されなかった場合には自動的にエレベータが復旧され、エレベータに異常が検出された場合には外部のエレベータの保守会社に通報されて適切な処理が施される。   When the elevator controlled in this way is subjected to earthquake shaking, seismic control operation is performed and each elevator stops. After each elevator is stopped, an earthquake recovery diagnosis operation is performed, and these stopped elevator cars are run to check whether there is an abnormality and perform a recovery diagnosis. When no abnormality is detected in the elevator, the elevator is automatically restored. When an abnormality is detected in the elevator, the elevator maintenance company is notified and appropriate processing is performed.

しかし、上述したエレベータの復旧の診断を行う際に、複数台のエレベータのかごを走行させて同時に診断運転し、異常の有無の確認を行うと、各エレベータの診断運転による走行の影響でエレベータの異常が誤検出される問題があった。そこで、複数台のエレベータの開始順序を決めて診断運転を順に行うことによってこの種の異常の誤検出を防ぐエレベータの制御装置が知られている(例えば、特許文献1参照)。   However, when diagnosing the restoration of the elevator described above, if a plurality of elevator cars are run and simultaneously run in a diagnostic operation to check whether there is an abnormality, the elevators are affected by the running of the diagnostic operation of each elevator. There was a problem that anomalies were detected incorrectly. Therefore, there is known an elevator control device that prevents erroneous detection of this type of abnormality by determining the start order of a plurality of elevators and sequentially performing diagnostic operation (see, for example, Patent Document 1).

特開2008−7237号公報JP 2008-7237 A

ここで、エレベータのかごと制御盤との間には、多数の通信ケーブルや電源ケーブル等を重ねて1本に形成した移動ケーブルが接続されている。そのため、エレベータが地震の揺れを受けると、移動ケーブルが昇降路内に設置された機器に引っ掛かる場合がある。この場合、上述した特許文献1に開示されたエレベータの制御装置によって運転制御されたエレベータに地震復旧診断運転を実施させると、全てのエレベータがそれぞれ走行して診断運転を行う結果、引っ掛かった移動ケーブル及びこの移動ケーブルに引っ掛けられた昇降路内の機器、すなわちエレベータ機器類が破損し、エレベータが故障する問題がある。これにより、地震発生後のエレベータの利用者のサービス性が著しく低下する虞がある。特に、エレベータの台数が少ない場合にエレベータが故障すると、エレベータが復旧するまでに時間が掛かり、この間エレベータを使用することができず不便である。   Here, between the elevator car and the control panel, a plurality of communication cables, power cables and the like are formed as a single moving cable. For this reason, when the elevator is subjected to an earthquake shake, the moving cable may be caught by equipment installed in the hoistway. In this case, when the elevator whose operation is controlled by the elevator control device disclosed in Patent Document 1 described above is subjected to the earthquake recovery diagnosis operation, the result is that all the elevators run and perform the diagnosis operation. And the apparatus in the hoistway hooked by this moving cable, ie, an elevator apparatus, is damaged, and there exists a problem which an elevator breaks down. Thereby, there exists a possibility that the serviceability of the elevator user after an earthquake occurrence may fall remarkably. In particular, if the number of elevators is small and the elevator breaks down, it takes time until the elevator is restored, and the elevator cannot be used during this time, which is inconvenient.

本発明は、このような従来技術の実情からなされたもので、その目的は、事故発生後の危険度が少なく復旧の可能性の最も高いエレベータに地震復旧診断運転を実施させることができるエレベータの制御装置を提供することにある。   The present invention has been made based on the actual situation of the prior art as described above. The purpose of the present invention is to provide an elevator that can perform an earthquake recovery diagnosis operation to an elevator that has a low risk after an accident and has the highest possibility of recovery. It is to provide a control device.

上記の目的を達成するために、本発明のエレベータの制御装置は、群管理運転制御される複数台のエレベータのそれぞれを、地震発生時に所定以上の揺れがあったときに地震管制運転させ、この地震管制運転により休止したエレベータを監視装置を介して、復旧の要否を判定する地震復旧診断運転させる運転制御を行うエレベータの制御装置において、地震発生時の前記複数台のエレベータの稼働状況を記録する稼働状況記録手段と、この稼働状況記録手段で記録される前記複数台のエレベータそれぞれの稼働状況から、前記地震復旧診断運転させる1台の特定エレベータを決める判定を行う優先順位判定手段と、この優先順位判定手段によって判定された前記特定エレベータの前記地震復旧診断運転を実施させる指令を出力する診断運転指令手段とを備え、前記稼働状況記録手段に記録される前記稼働状況は、地震発生時に前記エレベータが走行中か停止中かを確認する走行状況と、地震発生時に前記エレベータのかごの位置を確認する位置状況とを含み、前記優先順位判定手段は、前記稼働状況記録手段で1台のエレベータのみが停止中と記録されているときは、そのエレベータを前記特定エレベータと判定し、前記稼働状況記録手段で複数台のエレベータが停止中と記録されているときは、前記複数台のエレベータのうち最下階に最も近いエレベータを前記特定エレベータと判定し、前記稼働状況記録手段で全てのエレベータが走行中と記録されているときは、最下階に最も近いエレベータを前記特定エレベータと判定することを特徴としている。 In order to achieve the above object, the elevator control apparatus according to the present invention causes each of a plurality of elevators to be controlled in group management operation to perform seismic control operation when there is a predetermined swing or more when an earthquake occurs. Records the operating status of the multiple elevators when an earthquake occurs in an elevator control device that performs operation control to make an earthquake recovery diagnosis operation to determine whether restoration is necessary for an elevator that has been suspended due to earthquake control operation Operating status recording means, and priority order determining means for determining which one specific elevator to perform the earthquake recovery diagnosis operation from the operating status of each of the plurality of elevators recorded by the operating status recording means, A diagnostic operation indicator that outputs a command to execute the earthquake restoration diagnosis operation of the specific elevator determined by the priority determination unit And means, the operating status to be recorded in the operational status recording device checks the running status to ensure the elevator during the earthquake or stopped or running, the position of the car of the elevator in the event of an earthquake The priority order determining means determines that the elevator is the specific elevator when only one elevator is recorded as being stopped by the operating status recording means, and the operating status recording means When a plurality of elevators are recorded as being stopped, the elevator closest to the lowest floor among the plurality of elevators is determined as the specific elevator, and all the elevators are traveling by the operating status recording means Is recorded, the elevator closest to the lowest floor is determined as the specific elevator .

このように構成したエレベータの制御装置は、エレベータが地震の揺れを受けて地震管制運転が行われて休止したとき、これらの休止したエレベータのうち稼働状況記録手段に記録された各エレベータの稼働状況から、地震の揺れで引っ掛かった移動ケーブル及びこの移動ケーブルに引っ掛けられた昇降路内の機器、すなわちエレベータ機器類が破損する可能性が最も低いエレベータを優先順位判定手段で特定し、診断運転指令手段の指令によってこの特定された特定エレベータから優先的に地震復旧診断運転を実施させることができる。   The elevator control apparatus configured as described above is the operation status of each elevator recorded in the operation status recording means among the stopped elevators when the elevator is subjected to earthquake control operation and stopped due to the earthquake. From the moving cable caught by the shaking of the earthquake and the equipment in the hoistway hooked by this moving cable, that is, the elevator that has the lowest possibility of damaging the elevator equipment is specified by the priority determination means, and the diagnostic operation command means The earthquake restoration diagnosis operation can be carried out preferentially from the specified specific elevator specified by the command.

そのため、地震の揺れによって移動ケーブルが昇降路内に設置された機器に引っ掛かることが予想される場合でも、これらエレベータ機器類が破損する可能性が高いエレベータの地震復旧診断運転を実施させる前にこれらのエレベータを復旧させるかどうかを判断することができる。このように、事故発生後の危険度が少なく復旧の可能性の最も高いエレベータに地震復旧診断運転を実施させることができ、エレベータ機器類が破損することを抑えることができる。また、本発明は、稼働状況記録手段に記録された各エレベータの走行状況及び位置状況に基づいて優先順位判定手段で特定エレベータを決定し、優先的に地震復旧診断運転を実施させることができるので、煩雑な設定作業を必要とせず、使い勝手が良い。さらに、本発明は、優先順位判定手段が位置状況よりも走行状況を最優先の判定基準とすることにより、エレベータ機器類が破損する可能性が最も低いエレベータを容易に判定することができる。そして、優先順位判定手段が走行状況の次に位置状況を判定基準とすることにより、確実に1台の特定エレベータを決める判定を行うことができるので、誤作動を生じさせることなく装置の安定性を向上させることができる。 For this reason, even if it is expected that the moving cable will be caught by equipment installed in the hoistway due to the shaking of the earthquake, these elevator equipments are likely to be damaged. It can be determined whether to restore the elevator. In this way, it is possible to cause the elevator having a low risk after the occurrence of the accident and having the highest possibility of recovery to perform the earthquake recovery diagnosis operation, and it is possible to prevent the elevator equipment from being damaged. Further, according to the present invention, it is possible to determine the specific elevator by the priority order determination means based on the traveling condition and position situation of each elevator recorded in the operating condition recording means, and to make the earthquake restoration diagnosis operation preferentially performed. It does not require complicated setting work and is easy to use. Furthermore, according to the present invention, the priority determining unit can easily determine the elevator with the lowest possibility of damaging the elevator equipment by using the traveling condition as the highest priority determination criterion rather than the position condition. Then, since the priority order judging means uses the position situation as the judgment criterion next to the running situation, it is possible to make a decision to reliably determine one specific elevator, so that the stability of the apparatus can be prevented without causing a malfunction. Can be improved.

本発明に係るエレベータの制御装置は、前記発明において、前記監視装置は、前記稼働状況記録手段と、前記優先順位判定手段と、前記診断運転指令手段とを含むことを特徴としている。このように構成すると、稼働状況記録手段、優先順位判定手段及び診断運転指令手段のこれら3つの手段を1つのデバイスにまとめることができるので、コンパクトに収容することができる。   The elevator control device according to the present invention is characterized in that, in the above invention, the monitoring device includes the operation status recording means, the priority order determination means, and the diagnostic operation command means. If comprised in this way, since these three means of an operation condition recording means, a priority order determination means, and a diagnostic operation command means can be put together in one device, it can accommodate compactly.

本発明のエレベータの制御装置は、地震が発生して所定以上の地震の揺れを受けると、地震管制運転が行われて各エレベータが休止する。そして、稼働状況記録手段に記録された各エレベータの稼働状況から、優先順位判定手段でこれらのエレベータのうち移動ケーブル等のエレベータ機器類が破損する可能性が最も低いエレベータを1台の特定エレベータに決める判定を行う。特定エレベータが決められると、診断運転指令手段によってこの特定エレベータの地震復旧診断運転を実施させる指令が出力され、特定エレベータの地震復旧診断運転が実施される。   In the elevator control device of the present invention, when an earthquake occurs and a predetermined or greater earthquake is shaken, the earthquake control operation is performed and each elevator is stopped. Then, from the operating status of each elevator recorded in the operating status recording means, the priority determining means sets the elevator that has the lowest possibility of damaging elevator equipment such as moving cables among these elevators to one specific elevator. Make a decision to decide. When the specific elevator is determined, the diagnostic operation command means outputs a command to execute the earthquake restoration diagnosis operation of the specific elevator, and the earthquake restoration diagnosis operation of the specific elevator is performed.

そのため、地震の揺れによって移動ケーブルが昇降路内に設置された機器に引っ掛かることが予想される場合でも、エレベータ機器類が破損する可能性が最も低い特定エレベータを優先的に地震復旧診断運転させることができるので、復旧させるエレベータを確保することができると共に、エレベータ機器類が破損する可能性が高いエレベータを地震復旧診断運転を実施させる前に復旧させるかどうかを判断することができる。これにより、事故発生後の危険度が少なく復旧の可能性の最も高い特定エレベータに地震復旧診断運転を実施させることができ、この特定エレベータによるエレベータ機器類の破損を抑えることができる。   Therefore, even if it is expected that the moving cable will be caught by equipment installed in the hoistway due to the shaking of the earthquake, the earthquake restoration diagnosis operation should be given priority to the specific elevator that is least likely to damage the elevator equipment. Therefore, it is possible to secure an elevator to be restored and to determine whether or not to restore an elevator that is likely to be damaged by the elevator equipment before the earthquake restoration diagnosis operation is performed. As a result, the earthquake recovery diagnosis operation can be performed on the specific elevator having the lowest risk after the occurrence of the accident and the highest possibility of recovery, and it is possible to suppress the damage of the elevator equipment caused by the specific elevator.

したがって、特定エレベータを通常運転に復帰させることができ、地震発生後におけるエレベータの利用者のサービス性を向上させることができる。   Therefore, the specific elevator can be returned to normal operation, and the serviceability of the elevator user after the occurrence of the earthquake can be improved.

そして、これらエレベータ1A,11Aの各制御盤3,13は群管理盤20に接続されており、エレベータ1A,11Aが群管理制御されている。また、これら各制御盤3,13はエレベータ1A,11Aの状況を監視し、地震復旧診断運転等の指令をそれぞれ入出力する監視装置4,14に接続されており、さらにこれら監視装置4,14は互いに接続されて各エレベータ1A,11Aの情報をそれぞれ送受信する。   The control panels 3 and 13 of these elevators 1A and 11A are connected to the group management panel 20, and the elevators 1A and 11A are group-controlled. The control panels 3 and 13 are connected to monitoring devices 4 and 14 for monitoring the status of the elevators 1A and 11A and inputting / outputting commands such as earthquake restoration diagnosis operation. Are connected to each other and transmit / receive information of the elevators 1A and 11A, respectively.

また、監視装置4は、制御盤3等からの指令及び各種の情報を送受信する入出力装置4Dと、地震発生時の2台のエレベータ1A,11Aの稼働状況を記録する稼働状況記録手段、例えばRAM4C及びROM4Bと、これら入出力装置4D、RAM4C及びROM4Bから受信した情報に基づいて適切な処理を施す処理装置4Aとを有している。   The monitoring device 4 includes an input / output device 4D that transmits and receives commands and various information from the control panel 3 and the like, and operating status recording means that records the operating status of the two elevators 1A and 11A when an earthquake occurs, for example, A RAM 4C and a ROM 4B, and a processing device 4A that performs appropriate processing based on information received from the input / output device 4D, the RAM 4C, and the ROM 4B are provided.

さらに、処理装置4Aは、RAM4C及びROM4Bで記録される2台のエレベータ1A,11Aそれぞれの稼働状況から、地震復旧診断運転させる1台の特定エレベータを決める判定を行う優先順位判定手段と、この優先順位判定手段によって判定された特定エレベータの地震復旧診断運転を実施させる指令を出力する診断運転指令手段とを備えている。   Further, the processing device 4A includes priority order determination means for performing determination to determine one specific elevator to be operated for earthquake recovery diagnosis from the operating status of each of the two elevators 1A and 11A recorded in the RAM 4C and the ROM 4B.

ここで、稼働状況は、地震発生時にエレベータ1A,11Aが走行中か停止中かを確認する走行状況と、地震発生時にエレベータ1A,11Aのかご1B,11Bの位置を確認する位置状況とを含んでいる。   Here, the operation state includes a traveling state for confirming whether the elevators 1A and 11A are traveling or stopped when the earthquake occurs, and a positional state for confirming the positions of the cars 1B and 11B of the elevators 1A and 11A when the earthquake occurs. It is out.

以下、本発明の一実施形態によって運転制御されたエレベータ1A,11Aが所定以上の地震の揺れを受けたときの動作を図2、図3に基づいて説明する。   Hereinafter, the operation when the elevators 1A and 11A whose operation is controlled according to the embodiment of the present invention is subjected to an earthquake shake of a predetermined level or more will be described with reference to FIGS.

図2に示すように、地震が発生してエレベータ1A,11Aが所定以上の揺れを受けると(S100)、地震感知器10が地震情報を制御盤3,13へ出力する。この地震情報を受けた制御盤3,13は、かご1B,11Bをそれぞれ最寄階に停止させ、かご1B,11B内の乗客が降りた後にドア2,12を閉めさせる。   As shown in FIG. 2, when an earthquake occurs and the elevators 1 </ b> A and 11 </ b> A are shaken more than a predetermined value (S <b> 100), the earthquake detector 10 outputs earthquake information to the control panels 3 and 13. Upon receiving this earthquake information, the control panels 3 and 13 stop the cars 1B and 11B on the nearest floor, and close the doors 2 and 12 after the passengers in the cars 1B and 11B get off.

そして、地震発生時のエレベータ1A,11Aの稼働状況が制御盤3,13を介してそれぞれ監視装置4,14に送信され、各RAM4C,14Cに格納される(S101)。   The operating status of the elevators 1A and 11A at the time of the earthquake is transmitted to the monitoring devices 4 and 14 via the control panels 3 and 13, respectively, and stored in the RAMs 4C and 14C (S101).

次に、エレベータ11Aの監視装置14は、RAM14Cに格納されたエレベータ11Aの稼働状況を監視装置4へ送信してRAM4Cに格納する(S102)。   Next, the monitoring device 14 of the elevator 11A transmits the operating status of the elevator 11A stored in the RAM 14C to the monitoring device 4 and stores it in the RAM 4C (S102).

次に、一定時間経過後(S103)、監視装置4の処理装置4AがRAM4Cに格納されたエレベータ1A,11Aの稼働状況から、地震復旧診断運転させる1台の特定エレベータを決める判定を行い、診断運転指令手段によってこの特定エレベータの地震復旧診断運転を実施させる(S104)。   Next, after a lapse of a certain time (S103), the processing device 4A of the monitoring device 4 determines from the operating status of the elevators 1A and 11A stored in the RAM 4C to determine one specific elevator for earthquake recovery diagnosis operation, and diagnoses it. This specific elevator is caused to perform earthquake restoration diagnosis operation by the operation command means (S104).

このとき、図3に示すように、優先順位判定手段は、RAM4C及びROM4Bに格納された2台のエレベータ1A,11Aの走行状況が停止中あるいは走行中であるかを判定する(S200)。   At this time, as shown in FIG. 3, the priority order determination means determines whether the traveling state of the two elevators 1A and 11A stored in the RAM 4C and the ROM 4B is stopped or traveling (S200).

これら2台のエレベータ1A,11Aのうち少なくとも一方の走行状況が停止中である場合、優先順位判定手段は2台のエレベータ1A,11Aのうち走行状況が停止中のエレベータが1台のみであるかどうかを判定する(S201)。   If at least one of the two elevators 1A and 11A is in a stopped state, the priority determination means is only one of the two elevators 1A and 11A that has a stopped traveling state. It is determined whether or not (S201).

2台のエレベータ1A,11Aのうち走行状況が停止中のエレベータが1台のみである場合、この停止中のエレベータを特定エレベータと判定し(S203)、処理装置4Aが診断運転指令手段によってこの特定エレベータの地震復旧診断運転を実施させる(S204)。   When only one elevator is stopped in the traveling state of the two elevators 1A and 11A, the stopped elevator is determined as a specific elevator (S203), and the processing device 4A uses the diagnostic operation command means to specify this Elevator earthquake recovery diagnosis operation is carried out (S204).

一方、S200において2台のエレベータ1A,11Aの走行状況が共に走行中である場合及びS201において2台のエレベータ1A,11Aの走行状況が共に停止中である場合、これらのエレベータ1A,11Aのうち最下階に最も近いエレベータを特定エレベータと判定し(S202)、処理装置4Aが診断運転指令手段によって特定エレベータの地震復旧診断運転を実施させる(S204)。   On the other hand, when the traveling conditions of the two elevators 1A and 11A are both traveling in S200 and when the traveling conditions of the two elevators 1A and 11A are both stopped in S201, of these elevators 1A and 11A The elevator closest to the lowest floor is determined as the specific elevator (S202), and the processing device 4A causes the specific elevator to perform the earthquake restoration diagnosis operation by the diagnosis operation command means (S204).

このようにして特定エレベータ、例えばエレベータ1Aが特定エレベータと決定され、エレベータ1Aの地震復旧診断運転が実施されると、図2に示すように、エレベータ1Aの異常の有無を確認する(S105)。   When the specific elevator, for example, the elevator 1A is determined as the specific elevator in this way and the earthquake restoration diagnosis operation of the elevator 1A is performed, as shown in FIG. 2, the presence or absence of an abnormality in the elevator 1A is confirmed (S105).

エレベータ1Aに異常が有ることを確認した場合、エレベータ1Aを停止して復旧させず、エレベータ11Aの地震復旧診断運転を実施させずに終了する(S106)。一方、エレベータ1Aに異常が無いことを確認した場合、エレベータ1Aを通常運転に復旧させる(S107)。   When it is confirmed that there is an abnormality in the elevator 1A, the elevator 1A is stopped and not restored, and the elevator 11A is terminated without performing the earthquake restoration diagnosis operation (S106). On the other hand, when it is confirmed that there is no abnormality in the elevator 1A, the elevator 1A is restored to normal operation (S107).

なお、エレベータ1A以外の未復旧号機でのみサービス可能な階床がある場合、以下の処理手順で処理される。例えば、エレベータ11Aでのみサービス可能な階床がある場合、エレベータ11Aの地震復旧診断運転を実施させ(S109)、エレベータ11Aの異常の有無を確認する(S110)。   In addition, when there is a floor that can be serviced only by unrecovered units other than the elevator 1A, it is processed in the following processing procedure. For example, when there is a floor that can be serviced only by the elevator 11A, the earthquake recovery diagnosis operation of the elevator 11A is performed (S109), and whether or not there is an abnormality in the elevator 11A is confirmed (S110).

エレベータ11Aに異常が有ることを確認した場合、エレベータ11Aを停止して復旧させずに終了する(S106)。一方、エレベータ11Aに異常が無いことを確認した場合、エレベータ11Aを通常運転に復旧させる(S111)。   When it is confirmed that there is an abnormality in the elevator 11A, the elevator 11A is stopped and terminated without being restored (S106). On the other hand, when it is confirmed that there is no abnormality in the elevator 11A, the elevator 11A is restored to normal operation (S111).

このように構成した本発明の一実施形態によれば、S100においてエレベータ1A,11Aが所定以上の地震の揺れを受け、地震管制運転が行われて休止したとき、RAM4C及びROM4Bに記録された各エレベータ1A,11Aの稼働状況から、図3に示す処理手順に従い、監視装置4の優先順位判定手段が、S200及びS201において位置状況よりも走行状況が停止中であるかどうかを最優先の判定基準とし、S202において位置状況を第2の判定基準とすることにより、エレベータ機器類が破損する可能性が最も低いエレベータ1Aを誤作動が生じることなく容易に特定エレベータと判定することができる。   According to the embodiment of the present invention configured as described above, when the elevators 1A and 11A are subjected to earthquake vibrations of a predetermined level or more in S100, and the earthquake control operation is performed and stopped, each recorded in the RAM 4C and the ROM 4B is recorded. From the operating status of the elevators 1A and 11A, according to the processing procedure shown in FIG. 3, the priority determination means of the monitoring device 4 determines whether or not the traveling status is stopped rather than the position status in S200 and S201. By setting the position status as the second determination criterion in S202, it is possible to easily determine the elevator 1A that is least likely to damage the elevator equipment as a specific elevator without causing malfunction.

そして、処理装置4Aが診断運転指令手段の指令を出力し、このエレベータ1Aから優先的に地震復旧診断運転手段を実施させることにより、S105においてエレベータ1Aに異常が無いことを確認した場合に、S107においてこのエレベータ1Aを迅速に通常運転に復旧させることができるので、地震発生後におけるエレベータの利用者のサービス性を向上させることができる。   Then, when the processing device 4A outputs the command of the diagnostic operation command means and preferentially executes the earthquake restoration diagnosis operation means from the elevator 1A, it is confirmed in S105 that there is no abnormality in the elevator 1A. Since the elevator 1A can be quickly restored to normal operation, the serviceability of the elevator user after the occurrence of the earthquake can be improved.

さらに、S105においてエレベータ1Aに異常が有ることを確認した場合には、S106においてエレベータ1A,11Aを通常運転させることを停止する。すなわち、エレベータ1Aよりもエレベータ機器類が破損する可能性の高いエレベータ11Aの地震復旧診断運転を実施させる前にこのエレベータ11Aを復旧させずに終了する。これにより、エレベータ1A,11Aの通常運転、あるいはエレベータ11Aの地震復旧診断運転によってエレベータ機器類が破損することを防止することができる。   Furthermore, when it is confirmed in S105 that there is an abnormality in the elevator 1A, the normal operation of the elevators 1A and 11A is stopped in S106. That is, the elevator 11A is finished without being restored before the earthquake restoration diagnosis operation of the elevator 11A having a higher possibility of damaging the elevator equipment than the elevator 1A. Thereby, it is possible to prevent the elevator devices from being damaged by the normal operation of the elevators 1A and 11A or the earthquake recovery diagnosis operation of the elevator 11A.

このように、事故発生後の危険度が少なく復旧の可能性の最も高いエレベータ1Aに地震復旧診断運転を実施させることができ、エレベータ機器類が破損することを抑えることができる。   In this way, the earthquake recovery diagnosis operation can be performed on the elevator 1A having a low risk after the occurrence of an accident and the highest possibility of recovery, and it is possible to prevent the elevator equipment from being damaged.

また、本発明の一実施形態は、監視装置4は、例えばエレベータ1Aの稼働状況を記録するRAM4CとROM4B、優先順位判定手段、及び診断運転指令手段の3つの手段を含むコンパクトな構成とすることができる。また、監視装置14は、例えばエレベータ11Aの稼働状況を記録するRAM14CとROM14Bを備えているものの、優先順位判定手段及び診断運転指令手段を含まない簡単な構成とすることができる。   Further, in the embodiment of the present invention, the monitoring device 4 has a compact configuration including, for example, three means of a RAM 4C and a ROM 4B for recording the operating status of the elevator 1A, a priority order judging means, and a diagnostic operation command means. Can do. Moreover, although the monitoring apparatus 14 is provided with RAM14C and ROM14B which record the operating condition of the elevator 11A, for example, it can be set as the simple structure which does not include a priority order determination means and a diagnostic operation command means.

また、本発明の一実施形態は、上述したように監視装置4の処理装置4Aが優先順位判定手段によってエレベータ1A,11Aの走行状況及び位置状況だけで特定エレベータを決定することができるので、煩雑な設定作業を必要とせず、使い勝手が良い。   Further, in the embodiment of the present invention, as described above, the processing device 4A of the monitoring device 4 can determine the specific elevator only by the traveling state and the position state of the elevators 1A and 11A by the priority order determination unit. It is easy to use without requiring any setting work.
